Natural gas water heater installation requirements

Installing a gas water heater requires adequate planning during the water and electricity renovation stage of decoration. There are three pipelines related to gas water heaters: cold water inlet pipe, hot water outlet pipe, and gas inlet pipe. It should be noted that the positions of these three pipes are different for different models of gas water heaters. Therefore, you need to first determine the model of gas water heater you purchase, and then reserve the positions of these three pipes based on the actual model of the machine.

In addition, people often overlook one point: gas water heaters also need electricity. Therefore, a socket must be reserved for the gas water heater during decoration. It is best to use a socket with a switch and a waterproof cover.

Since water pipes generally go to the top, the hot and cold water outlets of gas water heaters usually go upwards, and the position of the pipes is usually exactly aligned with the center line of the water heater. Note here: Since fixing the gas water heater requires nailing on the wall, you should deliberately avoid the reserved nailing spots when routing pipes. Similarly, the circuit wiring of the socket reserved for the gas water heater should also be avoided. Nailing place.

Today’s gas water heaters are all forced exhaust type and need to be exhausted outdoors. The temperature of this gas is generally relatively high and plastic pipes cannot withstand it, so the exhaust pipes of gas water heaters are all made of metal. . Because metal has good thermal conductivity, this metal pipe is also very hot during actual use. Therefore, when installing the exhaust pipe, you should pay attention to avoid the exhaust pipe of the range hood, because the exhaust pipe of the range hood is made of plastic and is prone to aging and damage due to long-term local heating. The best design is for the metal pipe to go directly through the wall and not cross other rooms, such as the bathroom. Pay special attention, you must not walk through the flue! In order to avoid water intrusion on rainy days, the exhaust pipe should be slightly extended downward.

Some models of gas water heaters can be packaged in cabinets;Due to lack of air circulation, gas combustion may be incomplete and even frequent fire extinguishing may occur. You need to consult a professional as to which model can be covered and which model cannot be covered. Even if the gas water heater can be installed in the cabinet, its ventilation should be maximized. For example, the cabinet wall cabinets here should not have top and bottom plates, and no shutter doors should be installed.

Do not turn off the power when using the water heater in winter, because the automatic anti-freeze device inside it requires electricity for heating.

In addition: If the gas pipeline modification is not standardized, it may leak or even explode in the future, which will endanger the life and safety of you and your neighbors. Therefore, the state stipulates that only companies with professional qualifications can do this business.

Note: The gas pipeline must be exposed and cannot be wrapped. It is absolutely not allowed to block the gas pipeline with an aluminum gusset ceiling. The method to check whether the gas pipeline is leaking is the same as checking the car tires. Just apply soapy water to all joints and check if there are any bubbles.
